JOSEPH o. HUTcHIsoN, or PHILADELPHIA, PENNSYLVANIA.

MACHINE FOR" MAKING PIES.

To a, whom it may concern.-

Be it known that I, JOSEPH C. HUToHIsoN, a citizen of the United States,residing at Philadelphia, in the county of Philadelphia and State ofPennsylvania, have invented certain new and useful Im rovements inMachines for Making Pics, 0 which the following is a specification. v

My invention relates to that class of iemaking machines described andclaime in Letters Patent granted to David S. Williams, assignor toJoseph C. Hutchison, No.740,346, dated September 29, 1903, and LettersPatent No. 778,295, dated December 27, 1904, as also Letters Patentgranted to me, No.

786,816, dated April 11, 1905.

My present invention embodies improvements in the plate-feedingmechanism, the

mechanism for forming the upper and lower 2o pie-crusts, the fillermechanism, and in addition to these other details of construction whichwill be hereinafter fully described.

The essential features of my invention are, first, the construction of aplate-feeding mechanism which will handle plates which have become bentor twisted b use and which heretofore it has been found necessary tostraighten by an independent device before placing them in position tobe fed by a mechanism of the type shown and described in the patentsabove referred to; second, to provide means whereby the lungers may bemore uniformly heated; third, to provide a filler mechanism which willmore thoroughl 3 5 unite the fluid and solid mass of the filler beforeits delivery; fourth, to provide means for preventing the dough fromadhering to the several devices bywhich it is acted upon, and, fifth, toprovide means for ejecting the 0 finished product from the conveyer.

v The characteristic features of my present invention will be more fullyunderstood by reference to the accompanying drawings, in which Figure 1illustrates a side elevation of a machine embodying all the features ofmy invention. Fig. 2 is a plan view of the same with the upper portionof the filler mechanism broken away in order to better show its internalconstruction. Fig. 3 represents a front end elevation of the machine, atwhich point'is located the plate-feeding mechan ism. In this and inother similar views manyof the parts which would be seen in the 5 5distance have been purposely omitted in order to avoid a confusion oflines and to more Specification of Letters Patent.

Fig. 6 shows a vertical section taken on aline 6 6 of Fig. 1 and illustrates the construction of the heatingapparatus and the means employed to heat t nal section of the rearportions of the machine, taken on a line 7 7 of Fig. 2 and showing themechanism for discharging the finished product from the conveyer; and Fis. 8 and 9 are diagrammatic views showing the paths of the electriccircuit controlling the magnets of the plate-feeding mechanism.

Referring to the reference-letters of the drawings, A is the frame ofthe machine; B, the main drivin -shaft; 0, the endless conveyer; D, thep ate-feeding mechanism; E, the lower-crust-forming mechanism; F, thefiller mechanism; G, the uppercrust-form ing mechanism; H, the trimmingandcrimping mechanism, and I the ejector mechanism,

The main driving-shaft B is provided, respectively, with fast and loosedrivingpul leys B and B together with a pinion B the latter of whichmeshes with a gear-wheel B, mounted upon a shaft B The endless conveyerC is formed of a number of plates or links 0, which are hinged togetherand which have at the point of juncture rollers C which are supportedand guided upon rails C and C during the greater part of their travel.At the ends of the ma 0 e the conveyer is carried by sprocketwlieels Cand C, which are mounted, re-' spectively, upon shafts C and C journaledin bearings c and a which are fastened to the frame A. v I Y The shaft Cby which the conveyer C is driven, is provided with a ratchet-wheel Qoperated by a lever G which is fulcrumed upon the shaft C and isprovided with a spring-actuated awl 0 to engage the teeth The lever Cisconnected to a rod C operated by a, crank on the bevel-gearC which ismounted upon the shaft B The plates 0' of the conveyer C are eachPatented Nov. 13, 1906.

e plunger of the top-crust-forming mechanism. Fig. 7 represents alongitudirovided with a projecting ring or flange C ashioned in such amanner as to form a neatfitting support for a pie-plate, as well as aninner cutting edge for the crust-trimming dle of the trimming andcrimping mechanism.

The plate-feeding mechanism D comprises a bed-plate D supported uponbrackets D D, guides or uprights D fastened to the bed-plate'and servingas a means to keep a lar e number of platps in vertical alinement, an aplate-support D, upon which the plates rest and by which means they areelevated as the top plates are removed.

' The plate-support D is guided between the uprights D and is providedwith a centrally-disposed rack D guided in the bedplate D and acted uponby a pinion D, which receives motion through the medium of a train ofgearing operated from the shaft 6.

As shown in Figs. 1 and 3, the shaft C is provided with a srocket-wheel. D", which carries a sprocket-c ain D engaging a somewhatlarger sprocketwheel D", mounted upon a shaft D and journaled inhearings on the brackets D The shaft D is provided with a pinion D whichmeshes with a gear-wheel D fastened to a shaft D and by means of aclutch this shaft is caused to operate the pinion D and in turn the rackD When the plate D has been carried upward to the full extent of itsmovement and the pie-plates have been removed therefrom, it is obviousthat in order to repeat the operation the plate and its rack must belowered and replenished with a new stock of pie-plates. In order toaccomplish this, I mount the pinion D upon a sleeve (1, so that it maybefree to slide upon the. shaft D and provlde the sleeve with a handle(1", by which means it maybe manually operated to cause the pinion D toengage or disengage the shaft The clutch which I prefer to use in thisconnection com rises a toothed collar (1 pinned to the sha D and acorrespondinglytoothed hub 11, formed upon the pinion D, these twomembers being normally forced into engagement with eac other by a spiralspring which surrounds the sleeve d and is compressed between the pinionD and the frame A.

The means which I em by for lifting the 'lates one by one from t e pileand transfer-ring them to the conveyer is accomplished as follows:Fastened to one of the frames A to the left of the machine, as shown inFig. 3, is an arm D which is provided at the top with a stud-bolt d,carrying a short arm D to which is somewhat longer arm set ofelectromagnets ceives its backward and forward motion .by means of aconnecting-rod D", which is fulcrumed to a crank D, fastened to anupright shaft D, which shaft is caused to D", carrying a doublefulcrumed at a point d" a The arm D resaa'ise plate by reason of rotateby a-pair of bevel-gears D and D,

the former of which is secured to the shaft D and the latter to ahorizontal shaft B,

The shaft B derives its motion from the shaft B and the bevel-gear C bymeans of a bevel-gear C, with which it is provided and which reshes withthe bevel-gear C. I Returning to tprelalplate-feeding mechanism, the armD", it be noticed, is provided near the point to which it is fulcrumedto the arm D with a roller d", which rides upon a segmental cam d, whichis fastened to the arm D. The object of this cam is to permit themagnets to be lowered sufliciently close to the top plate in the pile toattract the same when the magnets are at the receiving end of theirtravel, also to lift the top plate clear of the next in order as the armmoves in the direction of the conveyer. At the discharge side, or thatto the left, (see Fig. 2,) the cam is also de ressed to enable themagnets to discharge t e plate as close to the conveyer as possible toassure the plates falling in proper alinement with the rings in theconveyer-sections. The arm D is provided with a switch-lever d,fulcrumed to it, and also with an insulated contact-plate d, which thearm enga es when the magnets are in position to pic u a pie-plate. Themovement of the switchever d is effected by means of projecting pins dand d, the former of which, as shown in Figs. 2 and 8, serves to closethe electric circuit and energizes the magnets to the oint of liftingone of the ie-plates, while t e latter serves to break t e circuit andallow the pie-plates to fall to the conveyer.

In the two ures above mentioned the arrangement of t e electric circuitis such that the current is open when the magnets are in the dischargingposition and closed when in a position to attract thus: Starting fromthe source of electromotive force, which I have indicated by thereference-letter W, the current would pass, say, over wire w, throu hthe electroma ets D and thence to t e contact-plate Then'if the magnetswere in a receiving position the current would pass through theswitch-lever d" and back over wire w to the starting-point.

In Fig. 9 I have illustrated a modified arrangement of the circuit whichnecessitates a reversal of the switch-lever and contactthe fact thatcurrent is never entirely broken, as in Fig. 8, but simply shunted bythe action of the switch-lever and contact-plate. In this figure it willbe readily seen that when the magnets are in a receiving position thecurrent will pass, say, from W, over the wire w, to the switch-lever d",thence over wire w to the electromagnets D and from there to thecontact-plates d" and then along wire w, throu h resistance R, back tothe starting-point. hen the position of the arm carrying The conve er isthen moved forwar is designed to -anism E. This mechanism, as will scansis reversed, as in thedelivery osition, the

current through the wire w. be ractically cut out -or rendered so weak ythe short circuit as to allow a plate carried by the electromagnets todrop to the conveyer.

The conveyer C after receiving a plate is carried forward to the extentof one link, and a iece of dough in the form of a cake or consi erablyless diameter than the crust itis to form is manually placed upon theie-plate. another step and t e cake of dough is brought under the actionof the lower-crust-formin he seen, com rises su porting frames A,between whic is firm y supported a bedlate E, arranged in line with andadapte to receive the greater part of the ressure imparted to theconveyer-plates: hesupporting-frame A also serves as guides to across-head E, which carries a lunger E shaped so as to mold a crust 'oft e requisite thickness in the pie-plate. The Eplunger E, as hereinshown, e heated by hot water or steam generated .in an independentreservoir or boiler and supplied by flexible connectingtubes.

As shown in Fig. 4 of the drawings, the

. lun er E contains an annular chamber e for the rece tion of hot wateror steam, preferably the ormer, which'is heated in a reservoir J by aBunsen burner J and conveyed to the plunger through a line of pipe andback again to the reservoir through a line of pipe j. The plunger E alsocontains an overflow-pipe e, which is open to the atmosphere when theheating device is being operated as a hot-water system, but which may beclosed by a valve 6 after allowing the air to escape in the event of thedevice being used as a steam-heating system. Located centrally withinthe plunger is a springin e, which is acted upon by a delicate spiraFSand serves to hasten the removal of a crust by pressing the same lightlyforward and destroying a partial vacuum set up between the crust andplunger.

The cross-head E which, is guided in the upper part of the frames A, isoperated by connecting-rods E fastened to crank-pins E one of which, asshown in the drawings, is secured to the face of a bevel-gear E, whilethe other issecured to a crank-disk E The bevel-gear E and thecrank-disk E are both mounted upon a shaft E, which is rotated by thebevel-gear E, engaging a corresponding gear E", mounted upon the shaftB.

The filler mechanism F, which is adapted to supply a measured quantityof fruit or meat to the already-formed lower crust, comprises a hopperF, fitted with hearing to receive' a reci rocating rod F, provided atthe bottom wit a plunger F and throughout a ortion of its length withmixing-pron s f This rod is operated from a shaft F y'a mech- I theother to a crank-disk G".

I crank-disk F and connecting-rod F, the said shaft belng provided witha driving-pulley F, which by means of a belt F may be driven from anyconvenient source of power. The contracted lower portion or mouth f 'ofthe hopper is connected to or may form an 1 integral part of a plate F",which, as shown, is supported above a bed-plate F by bolts f 8 in such amanner as to allow snug-fitting space for adisk F, which is free to turnupon a pivot-bolt F rovided in the resent case with four holes P f f,&c., (alt ough any number may be employed, if desired) and these holesare adapted to receive a measured quantity of filler, which as the diskis rotated is discharged by gravity through an opening f locateddirectly over the medial line of the conveyor. In order to facilitatethe discharge of filler through the opening in the bed-plate, the upperplate F is provided with a hole f which is located in alinement with oneof the holes The disk just mentioned is of the disk and that of thebed-plate at the point of discharge. The disk is provided with notches facted upon by a pawl F which pawl is mounted upon a sliding bar F,guided-in a portion of the bed-plate F The sliding bar F receives itsmotion from the crank D through the interposition of a connecting-rod Fwhich is fulcrumed to a bracket F bolted to said sliding bar. Thetop-crust-forming mechanism G, the next in order, embodies an endlessbelt or apron G,

carried by rollers G and G and by an end These rollers are mounted,respecr00 plate G". tively, on shafts g and 9 which are properly\journaled and are provided with sprocketwheels g and 9 connected by asprocketchain g".

The shaft 9 is rovided also with a sprocket wheel 9, which t ough theaid of a sprocketchain g and somewhat larger sprocket-wheel 9 receivesower from the shaft C. In addition to t e above-mentioned features thetop-crust-forming mechanism also embodies a crust-forming plunger Gsecured to a.

cross-head G, which latter is guided in frames or u rights A fastened,to the body of the maciiine. Below the apron G is a bed-plate G, whichextends across the machine .and is fastened to the u rights A Thisbed-plate serves to sustain the pressure of the lunger when a crust isbeing pressed upon t e belt .or a ron G.

The cross-head 1 is provided with and operated by oppositely-disposedconnectingrods G i'ulcrumed upon crank-pins G", oneof which is connectedto a bevel-gear G and parts are mounted upon a shaft G, driven by the enagement of a bevel-gear G -on the shaft with theabove-mentionedbevelgear G Both of these The plunger G like that of the low er-crustfforming mechanism, is designed to be heated frames A, serving as guidesto disk H of the shaft B by hot water or steam, and is therefore, asshown in Fig. 6, made in the form of a hollow shell, containing an innerchamber G for the reception of the heating is brought into communicationwith the reservoir J by means of pi es 9 and g. The plunger is alsoprovidecfwith an overflowpipe g, which 18 open to the atmosphere w enthe heating device is operated as a hotwater system, but which may beclosed after allowing air contained in the plunger to escape in theevent of the device being used in connection with steam by a valve 9After the upper crust has been pressed the belt G is moved a stepforward and the crust is brought under the action of a markingplate This plate is adjustably fastened to an arm V, which is bolted to theplunger and its function is to mark the crust wit-h a suitable letterdenoting the kind of filler contained in the finished product. The plateV is rovided with an arrangement of page 12, wln'c indent the crust andwhich are prevented from adhering to the same by means of a dustindevice located at the side of the machine. This dusting device consistsof a bellows V mounted upon an upright V a hopper V to contain aquantity of flour, and a lever V for operating the upper lid of thebellows. The bellows V is expanded 01' pressed open by an internalspring S and is closed to force out a jet of flour upon the pegs of themarking-plate by a cam V, fastened to the shaft B.

The lever V is slotted out, so that it may be guided upon the shaft B inthe Wellknown manner, and is provided with a roller '0 which restsagainst the face of 'the cam. The pie-crusts are next subjected to theaction of the trimmin and crimping mechanism, arranged as to lows:Fastened to the main frame A of the machine are upright a cross-head H,which carries a ring H which ring is designed to sever the uneven edgesof tne crusts by closely engaging and passin downward over the rings orflanges C of t 1e conveyer C. A second ring H secured within thefirst-mentioned rings, is designed to crimp the edge'of the crust, andby so doing to unite the upper and lower crusts firmly together.

The cross-head H is fulcrumed to rods H, which are connected at theirlower ends to crank-pins II", one of which is connected to thebevel-gear C and the other to a crank- At therdischarge end of themachine the pic-plates and their contents are removed by means of anejector I, (see Fig. 7,) which embraces a horizontal bar I. mounted inbearings i i and operated in one direction by a spiral spring S. Theaforesaid bar is caused to move in the opposite direction against theaction of the spring S by a crank I on the shaft B which crank fluld,which chamber is (provided with a pin adapted to act upon a og ifastened to the bar I.

As will be noticed in the drawings, each of the links or sections of theconvey er is provided witn a hole i, through which one end of the barI"projects when in the act of discharging a pie-plate from the conveyer.
